Per-Language Voice Selection
Assign a dedicated Text-to-Speech voice persona to each starting language directly from the agent’s Voice settings, replacing the need for hardcoded voice configuration. Enable Per-language voices (Overrides default voice) and define a conditional mapping for each language — for example, Mansi for Hindi, Cynthia for Odia, or Arjun Bhatt for English. At the start of a call, the agent selects the voice persona assigned to the starting language. The assigned speaker then remains consistent for the duration of the call, even if the caller switches languages mid-conversation.
Voice Lifecycle API
The voice library is now manageable over the API - no Studio visit required. POST /voices/create creates a cloned voice from a reference clip in one shot: the response returns the new voice_id and the auto-generated transcript (reference_text) together, and the voice is immediately usable with POST /voices/clone. GET /voices lists your voices, GET /voices/{voice_id} returns details with time-limited signed audio URLs, and DELETE /voices/delete/{voice_id} deletes a voice (freeing a slot against your tier’s voice cap). See Manage saved voices and the API Reference.
